Effect of non-invasive bilateral sphenopalatine ganglion block on postoperative pain in patients undergoing septorhinoplasty surgery: a randomized controlled study.

Background: The objective of this study was to assess the impact of preoperative sphenopalatine ganglion block (SPGB) on postoperative pain and assess intraoperative and postoperative analgesic consumption in patients undergoing septorhinoplasty.

Methods: In this prospective, randomized controlled study, 72 patients were included and divided into two groups: group 1 (36 patients) received the sphenopalatine ganglion block (SPGB), while group 2 (36 patients) served as the control group. Patient assessments, using the numerical rating scale (NRS), were conducted at the postoperative first hour, fourth hour, and 24 hour.

Investigation of proapoptotic and cytotoxic effects of 2-aminobenzothiazole on human laryngeal carcinoma cells.

Objective: In the present study, we investigated the effects of 2-aminobenzothiazole application on human laryngeal carcinoma cells.

Materials And Methods: Human larynx epidermoid carcinoma (HEp-2) (ATCC® CCL-23™) cells were purchased from American Type Culture Collection (ATCC, USA). Human larynx epidermoid carcinoma HEp-2 cells were cultured in complete Dulbecco's Modified Eagle's Medium (DMEM) supplemented with fetal bovine serum (FBS) (10%) and penicillin/streptomycin (1%) in a CO2 (5%) incubator under standard cell culture conditions.

Immune activity of Ki-67 during nasal polyp development.

Objective: Nasal polyps are non-cancerous, soft painless growth of nasal mucosa. In this study, our aim was to investigate the Ki-67 expression level in nasal polyps by immunohistochemical method.

Patients And Methods: 30 patients with nasal polyps were included in this study.

Audiological evaluation of the cochlear nerve with brainstem evoked response audiometry in patients with COVID-19.

Purpose: In this clinical study, it was aimed to prospectively evaluate the cochlear nerve with brainstem evoked response audiometry (BERA) in terms of audiological ailments in patients with COVID-19. Although the relationship of COVID-19 with tinnitus and hearing loss has been investigated since the day this infectious respiratory disease emerged, its relationship with BERA has not been fully demonstrated from a neurological perspective.

Methods: It was carried out on a group of patients who had COVID-19 in the last 6 months between February and August 2021 in Diyarbakır Gazi Yaşargil Training and Research Hospital.

Differentiation of Benign and Malignant Thyroid Nodules with ANFIS by Using Genetic Algorithm and Proposing a Novel CAD-Based Risk Stratification System of Thyroid Nodules.

The thyroid nodule risk stratification guidelines used in the literature are based on certain well-known sonographic features of nodules and are still subjective since the application of these characteristics strictly depends on the reading physician. These guidelines classify nodules according to the sub-features of limited sonographic signs. This study aims to overcome these limitations by examining the relationships of a wide range of ultrasound (US) signs in the differential diagnosis of nodules by using artificial intelligence methods.
